SNOW-PLOW.

Specification of Letters Patent.

Patented Aug/4, 190s.

Application filed September'25, 1906. Serial No. saeiso.

Be it known that I, AXENTI S. CERKEZ, F engineer, a subject of the King of Roumania, and a resident of Bacau, Roumania, have invented certain new and useful Improvements in Snow-Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

drawings, and to letters of reference marked tion. f hly invention relates to improvements in snow plows in which the snow is filst carried upward upon an inclined lane and then carrie' sidewise or backwarr s.

The object of myimprovements is to decreaselthe friction of the snow on the lateral walls the plow, whereby the snow moves almost ithio ut any friction through the plow so that the-apparatus cannot be choked. And for this pur' ose I construct the bottom and the side we. s',, or ,their surface, of a material having a verydow coeflicient of friction, and to which snow" does not easily adhere, such as varnished or polished wood, or enameled leather, or by causing said surfaces to move backwards.

The invention further-consists in an improved means to cut out the amount of snow corresponding to the dimensions of the plow, so that the plow willeasily overcome the resistance offered bythe snow. For this purpose I provide an irdn saw in front of the plow, which saw preferably consists of a steel wire, and which is actuated by the same motor which moves the'side and bottom walls of the a paratus.

In the accompanying rawings I have illustrated, as an example, an apparatus embodying my invention.

In said drawings :-Figure 1 is a. perspective view of the plow, Fig. 2 is a plan of the same, Fig. 3, a longitudinal cross section of the same, Fig. 4, a partial cross section, illustrating themeans to move the g bottom cross bars, Fig. 5', a cross section: on the line A-B of Fig. 4, 6, a view 5 illustrating the movable side walls, Fig. 7, a cross section on the line E.F of Fig. 6, and Fig. 8 a cross section on the line C-D Similar letters of reference refer to simi- 55 lar parts throughout the different views.

The platform 1 of the apparatus is arranged as an inclined plane having its lower l front. edge slightly above the bottom. In order to prevent the snow from adhering on the bottom, where a stationary bottom is used, cross bars 2 are provided which move o er'the platform from its front side to its rear end, whereby the snow is scratched off and carried to the rear end of the The cross-bars are referably guided on 1 longitudinal rails 5 {Fig 3) arranged below the platform, rollers 6 being provided on the arms 3 to decrease the friction. The vertical walls 10, and also the bottom where the scratching bars 2 are not used, consist of a material of very low coefficient of friction, to which snow does not easily adhere or} they maly be covered with a layer of such a matena ameled leather is most ap ropriate forthe purpose. Further to avoid loss by friction the side walls, or an a non constituting the side walls, can be ma e movable in sucha way, as to move backwards with the speed example of what may be done in this direcof the snow passing through the plow.

tion is shown in detail in Figs. 6 to 8. On the inner side of an apron 11 angle bars 12 are mounted within a certain distance from each other, which bars support two rollers 13, 14. The upper roller 13 rotates about a horizontal arm of the vertical angle bar 12,

while the lower one, 14, rotates about aver-1 tical arm. The angle bars 12, are connected,

with their inner surfaces, to' an endless chain 15, which is moved by a toothed wheel 16 which is actuated, by anintermediate chain and cham wheel mechanism, from the motor of the machlne. Thechmn 15, therefore,

carries along the angle Bars and the aoron The angle bars are guid d in U-1rons 1 1 17, having their web portions arranged horizontally and their flange portions extending downwards. On the hor zontal uppensurlow. 65 Sand cross bars are moved by any pre erred.

The latter is actuated, by a toothed wheel 7 wluch is-rotated from .the main motor driving the plow.

Experiments have shown that, en-

wheel 16 with the chain 15 and the U-iron 17 is sunk in thevertical side wall, whereby the latter is smooth on its inner surface and does not increase the resistance offered to The snow is carried over the inclined platform 1 and piled up on both sides of the road.

For this purpose vertical cross wallsare ar' ranged on the upper plate 18 of the plow, whereby the snow is moved sidewise. In the example shown, said walls are secured to the plate-1S by studs 26 engaging bore holes 20 of'the plate 18. Said studs and bore holes are, preferably, arranged in such a way, that the same cross wall can be arranged in both directions, so as to deflect the snow either to the right or to the left, or to both sides simultaneously. Also the cross walls are made of a material having a low coefficient of friction, or they may be provided with a movable a ron.

On the front side of t 1e plow a reamer 21 is. arranged, whereby the snow is moved sidewise, in case the snow is dee )er than the height of the plow. At the bac of the .ap aratus an auxiliary plow 22 is pro 'ided elow the platform 23 for the guide. By this arrangement, the apparatus can easily be moved back again, 1n case the snow should fall back again on the road.

In order to facilitate the cutting out of the amount of snow of a cross section corresponding to that of the plow, I provide a saw 24 in front of the apparatus, which, in the present example, consists of a steel wire moved along the vertical side walls and, preferably, also along the front edge of the bottom 1. Said In the exameach wall two times. a

The whole of the apparatus is mounted on a truck or framework 27, having wheels 28.

The latter are made of wood, or, if preferred,

of iron 29, covered on both sides with wood Any snow that may adhere to the wheels is removed by scratchers 31.

On the upper sides of the apparatus, I prefer to provide wings, whereby the upper margin of the snow walls produced by the plow is pres ed sidewise, so that the snow is prevented from falling down on the road.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States of America is:
